Starting at 7:30pm PDT/10:30pm EDT, we will webcast a special event around the launch of NASA's next lunar spacecraft. Watch our special coverage with lunar scientists and live video from the launch site, as well as NASA TV footage of the launch itself.
Just four months ago I posted about a paper recently published by Leslie Young and coauthors that described three possible scenarios for Pluto's atmosphere. Yesterday, Cathy Olkin, Leslie Young, and coauthors posted a preprint on arXiv that says that only one of those scenarios can be true. And it's a surprising one. The title of their paper says it all: "Pluto's atmosphere does not collapse."
NASA's Europa Mission Concept Rejects ASRGs -- May Use Solar Panels at Jupiter Instead
Untested technology is too risky
The Advanced Stirling Radioisotope Generator (ASRG) is no longer an option for powering a potential Europa mission. The ASRG uses Plutonium-238 to generate electricity, but is far more efficient than past RTGs.

From sols 373 to 383 (August 23 to September 3, 2013), Curiosity traveled about 250 meters toward Mount Sharp over five drives, trying out her new AutoNav capability.

In an enthralling article for Esquire magazine, astronaut Mike Massimino writes about nearly failing to repair the Hubble Space Telescope, and how the people of Earth came to his rescue.
There wasn't a dull moment for the Mars Exploration Rover mission in August as Opportunity drove up to the base of the Solander Point section Endeavour Crater's eroded rim, crossed over a geological boundary between ancient eras, maneuvered through a boulder field, scooting unscathed from a near-miss with a rock that could have ended it all, and at month's end delivered her team to what looks to be another scientific gemstone on the Red Planet.

Communication with the Deep Impact spacecraft was lost some time between August 11 and August 14. The team has determined the cause of the problem, and is trying to figure out how to restore communication.
What have the recent discoveries of thousands of exoplanets told us about how we got here, and whether we are alone? In Destiny or Chance Revisited, Stuart Ross Taylor attempts to answer those two questions.
It was announced this morning that Bill will be appearing as a contestant on the American hit show, “Dancing with the Stars”. I am so excited. "How will Bill fare?" you may ask. Consider the following...
Something remarkable has come up. I've been cast as a 'star' on Dancing With The Stars here in the US. (For our British readers, it's a very similar format to your Strictly Come Dancing.) As unusual as this may seem, I believe we can broaden awareness of the Society and thereby humankind's exploration of the Cosmos one ballroom dance at a time.
Bruce Murray was an early advocate for the inclusion of cameras on planetary spacecraft. As a tribute to him, I thought I'd take a look at a few of the images from the early Mariner missions to Mars.
An interview with Bruce Murray from 2001 about his perspectives on Mars science and exploration: past, present, and future.
NASA Backs Off From Additional Planetary Cuts in 2013
Operating plan provides $1.271 billion
The final operating plan for the space agency provided $75 million more to planetary exploration than initially proposed.
The Planetary Society is "making a difference" in the space industry, according to SpaceNews, the world's leading newspaper covering the space business.
The final news for NASA's Planetary Science program is better than had been proposed, but still a substantial cut over the previous year. There may be serious future consequences as a result of the smaller program.
Traveling confidently and alone, Dawn continues to make its way through the silent depths of the main asteroid belt. The interplanetary adventurer is on its long journey to the uncharted dwarf planet Ceres, by far the largest of all asteroids.
I am saddened by the loss of my professor and mentor, Bruce Murray. I celebrate him here by sharing some personal memories and reflections. There is much to respect, and also much to amuse as we reflect on the life of this great man.
